The veiled chameleon (Chamaeleo calyptratus) also known as the Yemen chameleon or cone-head chameleon, is a species of chameleon native to the mountain regions of Yemen, the United Arab Emirates, and Saudi Arabia. They are arboreal, living in upper tree regions and mountainous terrain at high altitude. Due to the veiled chameleons' popularity, distinctive appearance and hardy nature, they are often kept as exotic pets around the world, and befittingly they are the most commonly bred and available species of the genus in the reptile pet trade.
